Pharynx

The pharynx is a muscular tube that forms a passageway between the mouth and the esophagus and is part of both the respiratory and digestive systems. It plays an important role in breathing, swallowing, and speaking. In the respiratory system, it transports air from the nose or mouth to the larynx. In the digestive system, it transports food and liquids from the mouth to the esophagus. Its lining is covered with tiny, hair-like cilia, which are involved in the production of mucus. The pharynx also contains glands that help lubricate the food moving through it. Its size and location make the pharynx vulnerable to infection and irritation, leading to conditions such as pharyngitis and laryngitis.
